"11 x; 1 .iliftl '1 Lina! .11! 1.x". To e ul ilihio'rn-it'myconcm: I v.Befiflkn wnthat I, EDSON G. COVERT, of

New Kjensington, county of Vvestmoreland,

and State ofPennsylvania, have invented a newl and useful Improvement in Truck Side Frames, pf which the following is a full,

1 lea'm'na exact description, referencebeing "hadw the accompanying drawings, whichv form .part of this specification.

This invention relates to side frames for cartrucks, and it aims to provide a cheap and simple improved construction therefor.

The invention is directed to the construction and connectionof the journal boxes, and has particular reference to the type of journal' box and frame construction set forth in myapplication. filed July 28th, 1910, Serial I will ,now describe my invention so that othersskilled in the art to which it appertains may understand and construct the same. A I

Figure 1 is a sideelevation of a truck side frame embodying. my invention; Fig. 2 is a -vertical transverse section on the line 2--2 of Fig. 1; Fig. 3 is a top plan view, showing the frame member partly in section; Fig. 4' is a horizontal section taken on the line 44 of Fig. 2; Fig. 5 is a transverse section taken on the line 5-5 of Fig. 4; and Fig. 6 is a perspective view of the lug plate to be hereinafter referred to.

In the drawings the numeral 2 represents 'a truck frame, as shown in one piece, al-

though a frame of fabricated or built up construction may be used. This frame may beof any desired form or size, as this does not form part of my present invention. The

end portion of the frame is provided with a vertical web like portion 3, which, if desired, may be provided with the upper and lower flanges 4. This vertical member 3 1s provided with the opening 5, which receives the journal 6 of the car wheel.

As set forth in my application Serial No. 574,343, above mentioned, the journal box or casing proper is shown in the form of two sections 7 and 8; having flanges respectively 9 and 10 which lie in facial abutment with,

5 and are secured, preferably by we1ding,,to

the member'3 as shown in Figs. 2 and 4. Eaclll section 7 and 8 preferably compr1s es a sing e pressed sheet metal shell llke portion; .thesection 7 having the usual forward openin 11, which may be covered by any suitable form of journal box lid, and cover huge The stop lugs for the ,& .EDSON-O. covnnr, or ew. xnnsmeron, rnnnsvnvama.

Speciflcation ofIiet ters1atent. Pateflted 1H3, '7 Application filed August 20, 1910. Serial No. 578,183. 4 1 a? lugs 12. These hinge lugs 12 maybe riveted to theupper portion 13 of the box in the manner clearly shown in Figs. 2,-

and 5; the hinge lug through which the securing rivets 15 pass.

wedge plate are indicated'respectively by the numerals 16 and 17; the lug 16 being disposed atthe sides of the box and the lug 17 at the forward end of'the box in the usual manner. These lugs l6xand 17 are carried by the plate portion 18, which against the upper face ofthe'box'ra'nd the face 19 of the member 3 of the frame, and

may be held in position by means of the,

hinge lug rivets 15, as shown in Figs. 2 and 5.

As shown in F igs. 1, 4 and 5, the frame member 3 is provided with the inwardly pro ectmg portions20 against which the lu l6abuts and to which they maybe secure 'pref erably by welding. TliOs'e portions20, contacting with 'the lu 16, serve to greatly reinforce the lu s and operate for direct transmission on, to the vertical member 3 of the frame. It will also be noticed by referring to Fig. 2 that vertical stresses delivered to the lug plate 18 will in turn be transmitted substantially directly to the vertical member 3 of the frame and not indirectly through the journal box sections 7 and 8 insuch manner as to place shearing stresses thereon, by reason of the fact that the face 19 of the member 3 lies substantially flush with the inner face of the upper portion of the 'box sections.

The numeral 21 indicates a suitable dust guard plate having the flange portion 22, which is shouldered as at 23 so as to receive in abutment the edge .24. of the section 8. This section. 21 is, through the flange 23, preferably Welded to the section 8.

It will be apparent that many changes may be made in the construction shown Without departing from my invention.

While I have spoken of the several parts as being secured together by welding, which may be done electrically or otherwise, it will be apparent to the skilled mechanic that other fastening means may be employed for this purpose. WVhere the employment of the particular journal box construction shown, is desired with cast structures, Where welding is not feasible, said separate fastening means may be employed.

having the flange pOI'ti0Il14 bearing plate and lies inwardly of the stresses delivered there-' integrally formed lug plate carried bythe box. 1

readily appreciated The advantages of my invention will be by those skilled in the art. The construction is such as to enable the ready removal and replacement of the lug plate should it become worn, without disturbingthe rest of the box portions.

Having thus described my invention, what I claim and desire to secure by Letters Patent is,-- a

1. A truck side frame having a vertical member, a separately, formed ournal box secured thereto, and a separately 2. A truck side frame having a vertical member, a separately formed vertically divided two-part journal box secured thereto, and a lug plate carried by the box.

3..A-truck side frame having a vertical member, a separately formed journal box secured thereto and comprising a two-part casing mounted on opposite sides of the vertical member, and a separately formed lug plate carried by the box.

4. A truck side frame having a vertical member, a wrought metal'journal box, Weld- .secured thereto, and a separately formed lug plate carried by the box.

5. A truck side frame haying'a vertical member, aperturedfor the passage of the journal, a separately formed :journal box I secured to the vertical member, a lug portion carried by the vertical member and projecting inwardly in the box, and a lug plate carried by the box and having a lug disposed so as to lie in abutment with thelug of the vertical member.

6. A truck side. frame having a vertical portion apertured for the passage of the journal, at separately, nal box oppositely disposed the vertical portion, the vertical member and of the box, and a lug p box portion and having a as to lie in abutment with the of the vertical member.

7. A truck' side frame having a vertical portion apertured for the passage of the journal, a separately formed journal box secured thereto, a lug portion carried by the vertical member and projecting of the box, box and having a lug secured to the lug portion of the vertical member.-
